Spherical warp-based bubble with non–trivial lapse function and its consequences on matter content Classical Quant. Grav. (IF 3.5) Pub Date : 2024-04-25 G Abellán, N Bolívar and I Vasilev
In the present work, we study the consequences of including the lapse function as an additional degree of freedom for a general spherical warp-based geometry. By allowing a non-uniform lapse function to evolve, we find that it is possible to accommodate a fluid that includes heat flow. This broadens the range of fluid types that have been studied in these systems and is consistent with the spherical

Reduction of mechanical losses in ion-beam sputtered tantalum oxide thin films via partial crystallization Classical Quant. Grav. (IF 3.5) Pub Date : 2024-04-23 Giulio Favaro, Valeria Milotti, Diego Alonso Diaz Riega, Nicole Busdon, Marco Bazzan, Massimo Granata, David Hofman, Christophe Michel, Laurent Pinard, Livia Conti, Simone Capaccioli, Nikita S Shcheblanov, Anaël Lemaître, Valérie Martinez, Gianpietro Cagnoli, Francesco Piergiovanni, Federica Fabrizi, Maria G Pelizzo and Alain J Corso
This study explores the impact of crystalline fraction on the mechanical losses of amorphous tantalum oxide (tantala, Ta2O5) thin films intended for gravitational wave detectors. We use ion beam sputtering technique to prepare a series of samples, which are then subjected to controlled thermal annealing to achieve varying degrees of crystallized fraction. The microscopic structure of the annealed samples

Fuzzy bounces Classical Quant. Grav. (IF 3.5) Pub Date : 2024-04-23 Massimo Giovannini
We observe that the energy and the enthalpy densities can be smeared by two fudge factors that are constrained by the contracted Bianchi identities. Depending on the analytic properties of the smearing functions the underlying cosmological solutions belong to two physically different classes, namely the bounces of the scale factor and the curvature bounces. While the curvature bounces are naturally

Design of optical telescopes for laser field wavefront reconstruction in gravitational-wave detectors Classical Quant. Grav. (IF 3.5) Pub Date : 2024-04-23 A Allocca, E Genin, M Mantovani and A Chiummo
Pick-off beams in Interferometric Gravitational Wave Detectors are often used to derive information on the field circulating in the interferometer. In order to retrieve the wavefront of the field at some chosen location, an optical system has to be deployed so to image the desired field characteristics to an optical bench and ultimately to suitable sensors. In this paper, we detail the requirements

Gravitational wave pulse and memory effects for hairy Kiselev black hole and its analogy with Bondi–Sachs formalism Classical Quant. Grav. (IF 3.5) Pub Date : 2024-04-21 H Hadi, Amin Rezaei Akbarieh and David F Mota
The investigation of non-vacuum cosmological backgrounds containing black holes is greatly enhanced by the Kiselev solution. This solution plays a crucial role in understanding the properties of the background and its relationship with the features of the black hole. Consequently, the gravitational memory effects at large distances from the black hole offer a valuable means of obtaining information

Hybrid geometrodynamics: a Hamiltonian description of classical gravity coupled to quantum matter Classical Quant. Grav. (IF 3.5) Pub Date : 2024-04-21 J L Alonso, C Bouthelier-Madre, J Clemente-Gallardo and D Martínez-Crespo
We generalize the Hamiltonian picture of general relativity coupled to classical matter, known as geometrodynamics, to the case where such matter is described by a quantum field theory in curved spacetime, but gravity is still described by a classical metric tensor field over a spatial hypersurface and its associated momentum. Thus, in our approach there is no non-dynamic background structure, apart

Cosmology in Lorentzian Regge calculus: causality violations, massless scalar field and discrete dynamics Classical Quant. Grav. (IF 3.5) Pub Date : 2024-04-21 Alexander F Jercher and Sebastian Steinhaus
We develop a model of spatially flat, homogeneous and isotropic cosmology in Lorentzian Regge calculus, employing four-dimensional Lorentzian frusta as building blocks. By examining the causal structure of the discrete spacetimes obtained by gluing such four-frusta in spatial and temporal direction, we find causality violations if the sub-cells connecting spatial slices are spacelike.

Unveiling the cation ratio mediated structural modifications in TiO2:GeO2 mixtures for gravitational-wave detectors Classical Quant. Grav. (IF 3.5) Pub Date : 2024-04-21 Sangita Bhowmick, Ruth Osovsky, Aaron Davenport, François Schiettekatte, Martin Chicoine and Carmen S Menoni
Amorphous thin films of Ti doped GeO2 are of interest for coatings of the mirrors in gravitational wave detectors (GWDs) due to their low internal friction (Vajente et al 2021 Phys. Rev. Lett.127 071101). The addition of Ti to amorphous GeO2 (a-GeO2) enables tailoring of the optical and structural properties of the mixtures. However, the specific modifications that occur in the amorphous network with

Generalized K-essence inflation in Jordan and Einstein frames Classical Quant. Grav. (IF 3.5) Pub Date : 2024-04-21 Orlando Luongo and Tommaso Mengoni
We here explore a generalized K-essence model which exhibits characteristics akin to ordinary matter. The inflationary framework proposed aims to unify old with chaotic inflation into a single scheme and it considers minimally and non-minimally coupled scenarios, adopting three classes of potentials, in both Jordan and Einstein frames. We show that, to obtain a suitable amount of particles obtained

We construct a holographic dual theory of one-dimensional anisotropic Heisenberg spin chain, which includes two Chern-Simons gauge fields and a charged scalar field. Thermodynamic quantities of the spin chain at low temperatures, which are exactly calculated from the integrability, are completely reproduced by the dual theory on three-dimensional black hole backgrounds and the exact matching of the

We show that using Einstein equations it is possible to simplify and obtain general formulas for the surface gravity in terms of invariant quantities defined at these

Zeroth and second laws of black hole mechanics in Einstein-Maxwell-scalar effective field theory Phys. Rev. D (IF 5.0) Pub Date : 2024-04-23 Iain Davies
There has been recent progress in extending the zeroth and second laws of black hole mechanics to gravitational effective field theories (EFTs). We generalize these results to a much larger class of EFTs describing gravity coupled to electromagnetism and a real scalar field. We also show that the zeroth law holds for the EFT of gravity coupled to electromagnetism and a charged scalar field.

Maintaining spherical polarization in solar wind plasma Nat. Astron. (IF 14.1) Pub Date : 2024-04-22 Bishwanath Gaire
The solar wind consists of plasma with fluctuating velocity and magnetic fields in a manner often referred to as Alfvénic. A magnetic field (B) and its fluctuation (δB) with only a small change in its intensity (that is, δB/B ~1) is called spherical polarization. For large-amplitude magnetic fields, this condition (δB/B ~1) is equivalent to the rotation of the magnetic field vector. When the plasma

Magnetic Reconnection on Z experiments Nat. Astron. (IF 14.1) Pub Date : 2024-04-22 Bishwanath Gaire
Magnetic energy in magnetized plasma is converted into kinetic energy through magnetic reconnection; a phenomenon that commonly occurs in astrophysical plasma and has been observed in laboratory plasma. Radiative cooling can disrupt such an energy transfer process. Rishabh Datta et al. have studied strong radiative cooling in a laboratory experiment called Magnetic Reconnection on Z (MARZ), using the
